I’ve flashed two DB820c through Fastboot Method with Debian release 173 (Desktop distribution), and both DB820c work normally.
However, when these same DB820c are flashed with release 175 or 176 (the latest release), the HDMI display doesn’t work (keeps blank after boot).
Has anyone noticed any similar issue with the newest Debian Release? Or may have a clue on what may be wrong with the install method I’m using (listed below)?
[RELEASE 173] (kernel 4.11)
[RELEASE 175] (kernel 4.14)
[RELEASE 176] (kernel 4.14)
